基本上,我们试图通过Plumber将shiny的输出传递给其他程序员,以集成到网页中。
从文档中,在本地计算机上运行,以下工作分别:
管道工重复
#* Plot a histogram
#* @png
#* @get /plot
function(){
random_num <- rnorm(10) * 5
hist(random_num)
}
saving the file as plumber.R
# Running the below in console
r <- plumb("plumber.R") # Where 'plumber.R' is the location of the file shown above
r$run(port=8000)
# Now, loading the browser: http://127.0.0.1:8000/__swagger__/
[![plumber output][1]][1]
同样闪亮的reprex:
library(shiny)
# Define UI for application that plots random distributions
ui = shinyUI(fluidPage(
# Application title
titlePanel("Hello Shiny!"),
# Sidebar with a slider input for number of observations
sidebarLayout(
sidebarPanel(
sliderInput("obs",
"Number of observations:",
min = 1,
max = 1000,
value = 500)
),
# Show a plot of the generated distribution
mainPanel(
plotOutput("distPlot")
)
)
))
# Define server logic required to generate and plot a random distribution
server = shinyServer(function(input, output) {
# Expression that generates a plot of the distribution. The expression
# is wrapped in a call to renderPlot to indicate that:
#
# 1) It is "reactive" and therefore should be automatically
# re-executed when inputs change
# 2) Its output type is a plot
output$distPlot <- renderPlot({
# generate an rnorm distribution and plot it
dist <- rnorm(input$obs)
hist(dist)
})
})
# Run the app
shinyApp(ui, server)
如何将shiny的输出,即直方图渲染为plumber的swagger?
即如何显示用户
尝试:在Shiny的renderFunction中嵌入plumber函数
library(shiny)
# Define UI for application that plots random distributions
ui = shinyUI(fluidPage(
# Application title
titlePanel("Hello Shiny!"),
# Sidebar with a slider input for number of observations
sidebarLayout(
sidebarPanel(
sliderInput("obs",
"Number of observations:",
min = 1,
max = 1000,
value = 500)
),
# Show a plot of the generated distribution
mainPanel(
plotOutput("distPlot")
)
)
))
# Define server logic required to generate and plot a random distribution
server = shinyServer(function(input, output) {
# Expression that generates a plot of the distribution. The expression
# is wrapped in a call to renderPlot to indicate that:
#
# 1) It is "reactive" and therefore should be automatically
# re-executed when inputs change
# 2) Its output type is a plot
#### Embedding inside the shiny
output$distPlot <- renderPlot({
#* Plot a histogram
#* @png
#* @get /plot
function(){
# generate an rnorm distribution and plot it
dist <- rnorm(input$obs)
hist(dist)
}
})
})
shinyApp(ui, server)

您需要在ui/server定义之外干净地定义plotting函数。下面的代码可以作为shiny app使用,并且也可以被plumber正确解析:
